Members of the Freedom from Debt Coalition display placards while holding a protest in front of the United Nations office in Makati's financial district in Manila June 20, 2012. The protesters warned the Philippine delegation and world leaders attending the three-day Rio+20 Conference, also known as the United Nations Conference on Sustainable Development (UNCSD), in Rio de Janeiro, Brazil, not to fall into the trap of believing that the proposed "Green Economy" is "a tool and mechanism for sustainable development," according to the press statement.
